FIELD OF THE INVENTION

The present disclosure relates to: a) solid state forms of hydrobromide salts of (S)-2-(((S)-6,8-difluoro-1,2,3,4-tetrahydronaphthalen-2-yl)amino)-N-(1-(2-methyl-1-(neopentylamino) propan-2-yl)-1H-imidazol-4-yl)pentanamide (“Compound 1”); b) pharmaceutical compositions comprising one or more solid state forms of hydrobromide salts of Compound 1, and, optionally, a pharmaceutically acceptable carrier; c) methods of treating tumors or cancers by administering one or more solid state forms of hydrobromide salts of Compound 1 to a subject in need thereof; and d) methods for the preparation of solid state forms of hydrobromide salts of Compound 1.

BACKGROUND

(S)-2-(((S)-6,8-difluoro-1,2,3,4-tetrahydronaphthalen-2-yl)amino)-N-(1-(2-methyl-1-(neopentylamino) propan-2-yl)-1H-imidazol-4-yl)pentanamide (“Compound 1”) is a gamma-secretase inhibitor which can inhibit Aβ-peptide production.

Not all compounds that are gamma-secretase inhibitors have characteristics affording the best potential to become useful therapeutics. Some of these characteristics include high affinity at the gamma-secretase, duration of gamma-secretase deactivation, oral bioavailability, tissue distribution, and stability (e.g., ability to formulate or crystallize, shelf life). Favorable characteristics can lead to improved safety, tolerability, efficacy, therapeutic index, patient compliance, cost efficiency, manufacturing ease, etc.

In addition, the isolation and commercial-scale preparation of a solid state form of hydrobromide salts of Compound 1 and corresponding pharmaceutical formulations having acceptable solid state properties (including chemical stability, thermal stability, solubility, hygroscopicity, and/or particle size), compound manufacturability (including yield, impurity rejection during crystallization, filtration properties, drying properties, and milling properties), and formulation feasibility (including stability with respect to pressure or compression forces during tableting) present a number of challenges.

Accordingly, there is a current need for one or more solid state forms of hydrobromide salts of Compound 1 that have an acceptable balance of these properties and can be used in the preparation of pharmaceutically acceptable solid dosage forms.

DETAILED DESCRIPTION OF THE INVENTION I. Definitions

To facilitate understanding of the disclosure set forth herein, a number of terms are defined below.

Generally, the nomenclature used herein and the laboratory procedures in organic chemistry, medicinal chemistry, and pharmacology described herein are those well-known and commonly employed in the art. Unless defined otherwise, all technical and scientific terms used herein generally have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.

In this specification and the appended claims, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. The terms “a” (or “an”), as well as the terms “one or more,” and “at least one” can be used interchangeably herein. In certain aspects, the term “a” or “an” means “single.” In other aspects, the term “a” or “an” includes “two or more” or “multiple.”

Furthermore, “and/or” where used herein is to be taken as specific disclosure of each of the two specified features or components with or without the other. Thus, the term “and/or” as used in a phrase such as “A and/or B” herein is intended to include “A and B,” “A or B,” “A” (alone), and “B” (alone). Likewise, the term “and/or” as used in a phrase such as “A, B, and/or C” is intended to encompass each of the following aspects: A, B, and C; A, B, or C; A or C; A or B; B or C; A and C; A and B; B and C; A (alone); B (alone); and C (alone).

The term “Compound 1” refers to the single enantiomer (S)-2-(((S)-6,8-difluoro-1,2,3,4-tetrahydronaphthalen-2-yl)amino)-N-(1-(2-methyl-1-(neopentylamino) propan-2-yl)-1H-imidazol-4-yl)pentanamide.

The term “subject” refers to an animal, including, but not limited to, a primate (e.g., human), cow, sheep, goat, horse, dog, cat, rabbit, rat, or mouse. The terms “subject” and “patient” are used interchangeably herein in reference, for example, to a mammalian subject, such as a human subject.

The terms “treat,” “treating,” and “treatment” are meant to include alleviating or abrogating a disorder, disease, or condition, or one or more of the symptoms associated with the disorder, disease, or condition; or alleviating or eradicating the cause(s) of the disorder, disease, or condition itself.

The term “therapeutically effective amount” is meant to include the amount of a compound that, when administered, is sufficient to prevent development of, or alleviate to some extent, one or more of the symptoms of a disorder, disease, or condition being treated. The term “therapeutically effective amount” also refers to the amount of a compound that is sufficient to elicit the biological or medical response of a cell, tissue, system, animal, or human, which is being sought by a researcher, veterinarian, medical doctor, or clinician.

The terms “pharmaceutically acceptable carrier,” “pharmaceutically acceptable excipient,” “physiologically acceptable carrier,” or “physiologically acceptable excipient” refer to a pharmaceutically-acceptable material, composition, or vehicle, such as a liquid or solid filler, diluent, excipient, solvent, or encapsulating material. In one embodiment, each component is “pharmaceutically acceptable” in the sense of being compatible with the other ingredients of a pharmaceutical formulation, and suitable for use in contact with the tissue or organ of humans and animals without excessive toxicity, irritation, allergic response, immunogenicity, or other problems or complications, commensurate with a reasonable benefit/risk ratio. See Remington: The Science and Practice of Pharmacy, 21st Edition, Lippincott Williams & Wilkins: Philadelphia, Pa., 2005; Handbook of Pharmaceutical Excipients, 5th Edition, Rowe et al., Eds., The Pharmaceutical Press and the American Pharmaceutical Association: 2005; and Handbook of Pharmaceutical Additives, 3rd Edition, Ash and Ash Eds., Gower Publishing Company: 2007; Pharmaceutical Preformulation and Formulation, Gibson Ed., CRC Press LLC: Boca Raton, Fla., 2004 (incorporated herein by reference).

The terms “about” or “approximately” means an acceptable error for a particular value as determined by one of ordinary skill in the art, which depends in part on how the value is measured or determined. In certain embodiments, the term “about” or “approximately” means within 1, 2, 3, or 4 standard deviations. In certain embodiments, the term “about” or “approximately” means within 50%, 20%, 15%, 10%, 9%, 8%, 7%, 6%, 5%, 4%, 3%, 2%, 1%, 0.5%, or 0.05% of a given value or range.

The terms “active ingredient” and “active substance” refer to a compound, which is administered, alone or in combination with one or more pharmaceutically acceptable excipients, to a subject for treating, preventing, or ameliorating one or more symptoms of a condition, disorder, or disease. As used herein, “active ingredient” and “active substance” may be an optically active isomer of a compound described herein.

The terms “drug,” “therapeutic agent,” and “chemotherapeutic agent” refer to a compound, or a pharmaceutical composition thereof, which is administered to a subject for treating, preventing, or ameliorating one or more symptoms of a condition, disorder, or disease.

The term “solvate” refers to a compound provided herein or a salt thereof, which further includes a stoichiometric or non-stoichiometric amount of solvent bound by non-covalent intermolecular forces. Where the solvent is water, the solvate is a hydrate. Where the solvent includes ethanol, the compound can be an ethanol solvate.

The term “polymorph” as used herein refers to a crystalline form of a compound or a salt, hydrate, or solvate thereof, in a particular crystal packing arrangement. All polymorphs have the same elemental composition. The term “crystalline,” as used herein, refers to a solid state form which consists of orderly arrangement of structural units. Different crystalline forms of the same compound, or a salt, hydrate, or solvate thereof, arise from different packing of the molecules in the solid state, which results in different crystal symmetries and/or unit cell parameter. Different crystalline forms usually have different X-ray diffraction patterns, infrared spectra, melting points, density, hardness, crystal shape, optical and electrical properties, stability, and solubility. See, e.g., Remington's Pharmaceutical Sciences, 18^(th) ed., Mack Publishing, Easton Pa., 173 (1990); The United States Pharmacopeia, 23^(rd) ed., 1843-1844 (1995) (incorporated herein by reference).

Crystalline forms are most commonly characterized by X-ray powder diffraction (XRPD). An XRPD pattern of reflections (peaks, typically expressed in degrees 2-theta) is commonly considered a fingerprint of a particular crystalline form. The relative intensities of the XRPD peaks can widely vary depending on, inter alia, the sample preparation technique, crystal size distribution, filters, the sample mounting procedure, and the particular instrument employed. In some instances, new peaks may be observed or existing peaks may disappear, depending on the type of instrument or the settings. In some instances, any particular peak in an XRPD pattern may appear as a singlet, doublet, triplet, quartet, or multiplet, depending on the type of instrument or the settings, the sensitivity of the instrument, measuring conditions, and/or purity of the crystalline form. In some instances, any particular peak in an XRPD may appear in a symmetric shape or in an asymmetric shape, e.g., having a shoulder. Moreover, instrument variation and other factors can affect the 2-theta values. A skilled artisan understanding these variations is capable of discriminating or ascertaining the defining features or characteristics of a particular crystal form using XRPD, as well as using other known physicochemical techniques.

The term “amorphous” as applied to a compound refers to a state in which the material lacks long range order at the molecular level and, depending upon temperature, may exhibit the physical properties of a solid or a liquid. Typically such materials do not give distinctive X-ray diffraction patterns and, while exhibiting the properties of a solid, are more formally described as a liquid. Upon heating, a change from solid to liquid properties occurs which is characterized by a change of state, typically second order (“glass transition”).

The term “anhydrate” as applied to a compound refers to a solid state wherein the compound contains no structural water within the crystal lattice.

Unless the context requires otherwise, the terms “comprise,” “comprises,” and “comprising” are used on the basis and clear understanding that they are to be interpreted inclusively, rather than exclusively, and that Applicant intends each of those words to be so interpreted in construing this patent, including the claims below.

A hydrobromide salt form of Compound 1 can be prepared based on the synthetic schemes set forth in U.S. Pat. No. 7,795,447, which is incorporated herein by reference in its entirety. In some embodiments, the particular crystalline or amorphous form of hydrobromide salt of (S)-2-(((S)-6,8-difluoro-1,2,3,4-tetrahydronaphthalen-2-yl)amino)-N-(1-(2-methyl-1-(neopentylamino) propan-2-yl)-1H-imidazol-4-yl)pentanamide having the desired particle size is the product of the synthesis. In other embodiments, the particular crystalline or amorphous hydrobromide salt (S)-2-(((S)-6,8-difluoro-1,2,3,4-tetrahydronaphthalen-2-yl)amino)-N-(1-(2-methyl-1-(neopentylamino) propan-2-yl)-1H-imidazol-4-yl)pentanamide having the desired particle size is prepared using further processing steps following synthesis. Examples of such processing steps include, but are not limited to, recrystallization and milling, such as jet milling.

In some embodiments, the particle size is determined by laser diffraction (e.g., Sympatec Helos and QicPic) at 3.0 bar dispersion pressure.

Particle sizes for the crystalline materials may be assessed using laser diffraction methods. Laser diffraction is recognized by standards and guidance agencies including ISO and ASTM and is widely used to determine particle size distributions. In conducting the assessment, the sample is passed through a laser beam which results in laser light scattered at a range of angles. Detectors placed at fixed angles measure the intensity of light scattered at that position. A mathematical model (Mie or Fraunhoffer Theory) is then applied to generate a particle size distribution.

The particle size was analyzed using the laser diffraction (or small angle light scattering) technique by dispersing the dry sample powder with compressed air. Specifically, the particle size distribution was analyzed using the Sympatec HELOS RODOS system equipped with a Vibri dry powder feeder. The powder sample was dispersed with a dispersion pressure of 0.5 bar. In some instances, an Aspiros micro-dosing device was used, and the powder sample was dispersed with a dispersion pressure of 0.2 bar. A suitable lens was selected to cover the particle size range of each sample.

In particle size determinations, the median value is defined as the value where half of the population resides above this point, and half resides below this point. For particle size distributions the median is called the D50. The D50 is the size in microns that splits the distribution with half above and half below this diameter. The expression Dv50 or D[v,0.5] is sometimes used for the median of a volume distribution.

The mode is the peak of a frequency distribution. A particle distribution may include more than one mode, e.g., where the particles exist as primary particles and agglomerations.

The span is sometimes used as a measurement of distribution width and is defined as the ratio of (D[v,0.9]−D[v,0.1])/D[v,0.5] or (D90−D10)/D50.

The distribution width may also be characterized by citing one, two or preferably three values, typically some combination of the D10, D50, and D90. The D50, the median, has been defined above as the diameter where half of the population lies below this value. Similarly, 90 percent of the distribution lies below the D90, and 10 percent of the population lies below the D10.

The term D[4,3] refers to the volume mean or mass moment mean. Laser diffraction results are reported on a volume basis and the volume mean can be used to define the central point of the distribution. The D[4,3] value is sensitive to the presence of large particles in the distribution.

B. Experimental Methods Example 1: Approximate Kinetic Solubility

Weighed samples of material were treated with aliquots of specified solvents at ambient temperature. Samples were typically sonicated between additions to facilitate dissolution. Complete dissolution was observed through visual inspection. Solubility was calculated based on the total amount of solvent added to achieve complete dissolution and may be greater than the value reported due to incremental solvent addition and the inherent kinetics of dissolution. If dissolution was not observed, values are reported as “less than”. If dissolution was observed upon the first addition of solvent, values are reported as “greater than”. Table 1 shows kinetic solubility of dihydrobromide salt of (s)-2-(((s)-6,8-difluoro-1,2,3,4-tetrahydronaphthalen-2-yl)amino)-n-(1-(2-methyl-1-(neopentylamino)propan-2-yl)-1h-imidazol-4-yl)pentanamide.

Example 3: Polymorph Screen

Dihydrobromide salt of (s)-2-(((s)-6,8-difluoro-1,2,3,4-tetrahydronaphthalen-2-yl)amino)-n-(1-(2-methyl-1-(neopentylamino)propan-2-yl)-1 h-imidazol-4-yl)pentanamide, unless noted otherwise, was used as the starting material. Materials produced in the study were utilized for selected experiments.

Starting materials were subjected to crystallization techniques, which are summarized below. Solids were typically isolated by vacuum filtration, observed under polarized light and analyzed by XRPD.

Method a: Grinding Experiments

Solids were combined with small amounts of solvent and transferred to an agate milling container. An agate ball was added and the container attached to a Retsch mill. The sample was typically milled for either one cycle of twenty minutes at 30 Hz, or repacked and the cycle repeated for an additional 20 minutes.

Method b: Slurry Experiments

Solids were suspended in specified solvents. The suspensions were then agitated at ambient or set temperature. After a given amount of time solids were isolated.

Method c: Solvent/Anti-Solvent Precipitation

Solutions of starting material were prepared at ambient or elevated temperature and filtered using 0.2 μm nylon filters. They were then mixed with appropriate anti-solvents at elevated temperature. If no solids were observed, the samples were either cooled to ambient or sub-ambient temperatures or other crystallization techniques applied.

Method d: Crash Precipitation

Solutions of starting material were prepared at elevated temperature in specified solvents and hot-filtered through 0.2 μm nylon filters into appropriate anti-solvents pre-cooled on a dry ice/acetone or water/ice bath. If solids precipitated, they were immediately isolated by vacuum filtration while still cold. If the solution remained clear, the sample was either kept at sub-ambient temperatures or further crystallization techniques were applied.

Method e: Cooling Experiments

Solutions of starting material were prepared in specified solvents at elevated temperature using a hot plate for heating. These were typically hot-filtered through a 0.2 μm nylon filter into warm receiving vials. The vials were either quickly transferred into a sub-ambient temperature bath (typically dry ice/acetone) for crash cooling (CC), removed from the hot place for fast cooling (FC) or the heat was turned off to allow for slow cooling (SC). If solids precipitated, they were isolated cold by vacuum filtration. If the solution remained clear, the sample was either kept at sub-ambient temperatures or further crystallization techniques were applied.

Method f: Evaporation Experiments

Solutions of starting material were allowed to partially evaporate or evaporate to dryness at ambient or elevated temperature from open vials for fast evaporation (FE) or from vials covered with aluminum foil with pin holes for slow evaporation (SE).

Method a: Evaporation/Volume Reduction Experiments

Solutions of starting material were allowed to partially evaporate or evaporate to dryness at ambient or elevated temperature from open vials for fast evaporation (FE) or from vials capped loosely or covered with aluminum foil with pin holes for slow evaporation (SE). Prior to evaporation, solutions were filtered at ambient or elevated temperature using a 0.2 μm nylon filter.

Example 8: X-Ray Powder Diffraction (XRPD)

Method a: Transmission Geometry

XRPD patterns were collected with a PANalytical X'Pert PRO MPD diffractometer using an incident beam of Cu radiation produced using an Optix long, fine-focus source. An elliptically graded multilayer mirror was used to focus Cu Kα X-rays through the specimen and onto the detector. Prior to the analysis, a silicon specimen (NIST SRM 640d or 640e) was analyzed to verify the observed position of the Si 111 peak is consistent with the NIST-certified position. A specimen of the sample was sandwiched between 3-μm-thick films and analyzed in transmission geometry. A beam-stop, short antiscatter extension, and an antiscatter knife edge were used to minimize the background generated by air. Soller slits for the incident and diffracted beams were used to minimize broadening from axial divergence. Diffraction patterns were collected using a scanning position-sensitive detector (X'Celerator) located 240 mm from the specimen and Data Collector software v. 2.2b.

Method b. Reflection Geometry

XRPD patterns were collected with a PANalytical X'Pert PRO MPD diffractometer using an incident beam of Cu Kα radiation produced using a long, fine-focus source and a nickel filter. The diffractometer was configured using the symmetric Bragg-Brentano geometry. Prior to the analysis, a silicon specimen (NIST SRM 640d or 640e) was analyzed to verify the observed position of the Si 111 peak is consistent with the NIST-certified position. A specimen of the sample was prepared as a/thin, circular layer centered on a silicon zero-background substrate. Antiscatter slits (SS) were used to minimize the background generated by air. Soller slits for the incident and diffracted beams were used to minimize broadening from axial divergence. Diffraction patterns were collected using a scanning position-sensitive detector (X'Celerator) located 240 mm from the sample and Data Collector software v. 2.2b.

Example 9: Thermogravimetric Analysis (TGA)

TGA analyses were performed using a TA Instruments 2050 or a Discovery thermogravimetric analyzer. Temperature calibration was performed using nickel and Alumel™. Each sample was placed in an aluminum or platinum pan and inserted into the TG furnace. The furnace was heated under a nitrogen purge. The method code on the thermogram is an abbreviation for the start and end temperature as well as the heating rate; e.g., 25-350-10 means “from 25° C. to 350° C., at 10° C./min”.

Example 10: Differential Scanning Calorimetry (DSC)

DSC was performed using a TA Instruments Q2000 differential scanning calorimeter. Temperature calibration was performed using NIST-traceable indium metal. The sample was placed into an aluminum DSC pan (TOC), covered with a lid, and the weight was accurately recorded. A weighed aluminum pan configured as the sample pan was placed on the reference side of the cell. The method code on the thermogram is an abbreviation for the start and end temperature as well as the heating rate; e.g., −30-250-10 means “from −30° C. to 250° C., at 10° C./min”.

Example 11: Thermogravimetric-Infrared Spectroscopy (TG-IR)

Thermogravimetric infrared (TG-IR) analysis was performed on a TA Instruments thermogravimetric (TG) analyzer model 2050 interfaced to a Magna-IR 560® Fourier transform infrared (FT-IR) spectrophotometer (Thermo Nicolet) equipped with an Ever-Glo mid/far IR source, a potassium bromide (KBr) beamsplitter, and a mercury cadmium telluride (MCT-A) detector. The FT-IR wavelength verification was performed using polystyrene, and the TG calibration standards were nickel and Alumel™. The sample was placed in a platinum sample pan, and the pan was inserted into the TG furnace. The TG instrument was started first, immediately followed by the FT-IR instrument. The TG instrument was operated under a flow of helium at 90 and 10 cc/min, for the purge and balance, respectively. The furnace was heated under helium at a rate of 20° C./minute to a final temperature of 250° C. IR spectra were collected approximately every 32 seconds for approximately 13 minutes. Each IR spectrum represents 16 co-added scans collected at a spectral resolution of 4 cm⁻¹. Volatiles were identified from a search of the High Resolution Nicolet Vapor Phase spectral library. Searches from this library are considered non-cGMP.

Example 12: Polarized Light Microscopy (PLM)

Light microscopy was performed using a Leica DM LP microscope equipped with a SPOT Insight™ color digital camera. Typically, each sample was placed on a glass slide, a cover glass was placed over the sample, and a drop of mineral oil was added to cover the sample by capillarity. Each sample was observed using a 0.8-10.0× objective with crossed polarizers and a first order red compensator.

Example 14: Computational Methods (Indexing)

Successful indexing of an XRPD pattern indicates that the sample is composed primarily of a single crystalline phase. Agreement between allowed peak positions and observed peaks indicates a consistent unit cell determination. Indexing was performed using X'Pert High Score Plus 2.2a (2.2.1) and TRIADS™. No attempts at molecular packing were performed to confirm the tentative indexing solution within the scope of this work.
